CUTTER.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed June 15. 1907. Serial No. 379.280.

To all whom it may concern:

At the point of inter-section of the bit Be it known that we, CHARLES WV. SNOW with the frame, the outer edges of the secand HORACE H. SNow, citizens of the United States, residing at Truro, in the county of Barnstable and State of Massachusetts, have invented certain new and useful Improvements in Cutters; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to new and useful improvements in cutters, and more particularly to that class adapted to be employed for cutting washers from leather, or the like, and our object is to provide means for adjustably securing cutting blades to the frame of the cutter, whereby the sides and Width of the washer may be readily regulated.

A further object is to form the frame in two sections and provide means for operatively securing the sections together.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings which are made a part of this application, Figure 1 is a side elevation of our improved washer cutter complete. Fig. 2 is a top plan view thereof. Fig. 3 is a sectional view as seen on line 3--3, Fig. 1. Fig. 4 is a sectional view as seen on line 44, Fig. 1. Fig. 5 is a sectional view as seen on line 55, Fig. 1. Fig. 6 is a see- Fig. 7 is a perspective view of one section of the frame with the parts carried thereby, removed, and, Fig. 8 is a perspective view of an adjusting rod employed in adjusting the cutting knives on the frame.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates the bit of our improved washer cutter, which is secured at its lower end to a frame, said frame being formed in two sections 2 and 3, which are oblong and extended parallel to each other, the ends of said sections being, provided with inwardly extending members 4 and 5, respectively, while the central portion of said sections are provided with inwardly extending body portions 6 and 7, respectively, cavities 8 and 9 being formed between said body portions and end members and at opposite sides of the body portions.

tions 2 and 3 are provided with notches 10, in which are seated lugs 11 depending from the lower end of the bit 1, so that when the lugs are properly placed in the notches, the frame will be held rigid with respect to the bit and cause the same to rotate therewith, the lugs also serving to hold the meeting faces of the body portions 6 and 7 together.

As the sections 2 and 3 extend at right angles to the bit 1, and at a considerable distance to each side thereof, the outer ends of said sections are reinforced by means of bracearins 12 and 13, the upper ends of which are fixed to the bit 1 by directing a bolt 14 through the ends of the brace-arnrs and through the body of the bit, the bolt entering the bit at substantially its longitudinal center, while the opposite ends of the brace-arms are bifurcated to form shanks 15 and 16 on the brace-arms 12 and 13, respectively, and each of said shanks is provided with a bore 17, through which extend clamping bolts 18, the lower ends of said clamping bolts being threaded and entered in threaded bores 19 in the ends of the sections 2 and 3, and it will be readily seen that by so securing the brace-arms to the sections, the meeting edges of the inwardly extending members 4 and 5 will be securely held in engagement with each other and said sections prevented from separating.

Located at the longitudinal center of the sections 2 and. 3 is a spur 20, having at its upper end a threaded shank 21, which. extends upwardly through a socket formed in the meeting edges of the body portions 6 and 7 and into a threaded socket 22 in the lower end of the bit 1, said shank serving to hold the bit fixed to the frame.

Slidably mounted. in the cavities 8 and 9 are cross heads 23 and 24, which are provided at their opposite ends with channels 25, in which take the sections 2 and 3, thereby holding said cross heads against vertical or longitudinal movement and at the same time leaving the same free to move laterally in either direction.

The cross heads 23 and 24. are independently adjustable and are provided with cutting blades 26 and 27, respectively, which are adapted to travel in a circle around the spur 20 and. cut the object upon which the cutter is resting, and by spacing one of the so that said rods may be readily rotated,

while the inner ends of said rods are turned down, or reduced in size to form spindles 32, having formed. integral with their outer ends, circular disks 33, said spindles and disks being engaged by semicircular seats 34 in the meeting faces of the body portions 6 and 7, and when the body portions are fixed together, the semicircular seats entirely surround the spindles and disks, so that while the adjusting rods may be freely rotated, they will be held against longitudinal movement and by interiorly threading the openings 28, it will be readily understood that when the adjusting rods are rotated, the cross heads and cutting blades carried thereby will be moved towards or from the spur 20, thereby decreasing or increasing the dimensions of the washer.

In applying the cutting tool to use, we preferably employ the usual form ofbrace (not shown) to rotate the bit, and when cutting washers, the diameter of the spindle, or other objects upon which the washer is to fit, is ascertained, and one of the cutting blades moved the proper distance from the spurs 20, this cutting blade being employed to form the opening through the washer and by setting the opposite blade the proper distance from the spur 20, the body of the washer will be cut from the material at the .same time that the opening is formed in the washer, andby changing the location of the cutting blades, it will be seen that washers of various diameters and having different thicknesses between the periphery of the washer and the opening therethrough, may be obtained, and while we have described the device as employed for cutting washers, it will be readily understood that the same may be employed for cutting circular disks to be used in connection with various forms of valves, or the like, this result being accomplished by disposing both of the cutting blades an equal distance from the spur, so that both blades will travel in the same path.

It will further be seen that the cutting blades maybe renewed if, in any manner, they should become broken, and also that they may be removed from the frame and sharpened, the requirements necessary for removing the cutting blades being the removal of the clamping bolts 18 and the spur 20, when by dis-engaging the bit from the frame, the sections 2 and 3 may be readily separated and the cross-heads and adjusting rods released.

What we claim is:

1. In a cutter of the class described, the combination with a bit, having lugs at the lower end thereof; of a frame formed in sections and having notches in the outer edges thereof to receive said lugs, inwardly directed members at each end of said sections and body portions at the longitudinal center of said sections, said members and body portions forming cavities when the sections are placed together, cutting blades slidably mounted in said cavities, means to adjust said cutting blades in the cavities, a spur and means carried by the spur to secure said bit to the frame.

2. In a cutting device of the class described, the combination with a bit, having lugs at the lower end thereof; of a frame formed in sections, said frame having cavities between the sections, brace arms secured at one end to said bit and having their opposite ends bifurcated to form shanks, means to secure said shanks to the sections of the frame, whereby said frame will be held together, cross heads in said cavities, said cross heads having channels in each end thereof to receive said sections, the cross heads also having threaded openings therethrough, shafts extending longitudinally through said cavities and through the openings in the cross heads, cutting blades carried by said cross heads, spindles at one end of said rods, disks carried by said spindles'and seats in said sections to receive said spindles and disks to hold said rods against longitudinal movement.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
